UNITED STATES ATENT WALTER WESLEY EASTMAN AND HERBERT EDDIE POTTER, OF MILFORD,

IOWA.

GRAIN-BINDER.

SPECIFICATION forming part Of Letters Patent No. 401,644, dated April 16, 1889.

Application filed October 18, 1888. Serial No. 288,499. (No model.)

To 6055 whom it may concern.- Be it known that We, WALTER WEsLEY EASTMAN and HERBERT EDDIE POTTER, citizens of the United States, residing at Milford, in the county of Dickinson and State of Iowa, have invented a new and useful Improvement in Grain-Binders, of which the following is a specification.

Our invention relates to improvements in grain-binders, and has for its object the provision of means whereby the grain will be fed evenly to the binding-needle.

The invention consists in certain novel features, hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a perspective view of a portion of a grainbinder, showing our improvements applied thereto. Fig. 2 is a detail view of the movable deck and frame. Fig. 3 is a bottom plan view of the same. Fig. 4. is a section 9n the line a: :r of Fig. 2. Fig. 5 is a detail View showing the connection between the movable deck and the supporting-bar for the same.

Referring to the drawings by letter, A des- 2 5 ignates a grain-binder of the usual or any preferred construction, having an elevator, B, and a hood, O,at the upper end of the elevator. F designates our improved movable deck, which is arranged with its upper edge below the lower edge of the hood C and with its lower edge projecting over the stationary board G, secured to the binder-frame. shown.) At its upper end our movable deck is provided with the series of feeding-pins H, 3 5 which are adapted to engage the cut grain as it passes from the hood 0 and push it under the binding-needle. These feeding-pins are constructed, preferably, of malleable iron and have their front edges projected from the deck at a right angle thereto, and have their upper edges extending backward to the surface of the deck, thereby presenting an inclined side. By this construction, as the deck moves upward, the feeding-pins will pass under the grain, and as the deck moves downward the said pins will engage the grain and feed it to the binding mechanism. The deck is provided at its center with the usual transverse slots, I, for the passage of the packerarms and the intermediate slot, I, for the pas- (Not sage of the binding-needle in the operation of the machine. On its under side the movable deck is provided with the depending studs or pins, J, which engage longitudinally-slotted plates K, secured to the upper side of the sup- 5 5 porting-bars L, as shown. These slotted plates and the studs or pins engaging the same serve to guide the deck in its movements and secure a true and steady movement thereof. The supporting-barsL are connected at their upper and lower ends by the beams Q, and the upper one of said beams is secured to the harvester-frame, while the lower one is secured to the ,binder-frame, (not shown,) so that the deck will be supported in proper position. In order to support the deck above the plates K asufficient distance to allow the proper play of the crank-shaft, we secure to its under side the cleats or bars R, which rest on the plates K and support the deck above the same.

M designates a crank-shaft, which is journaled in suitable bearings on the supportingbars L, near the upper end of the elevator, and is connected with the lower under side of the movable deck by the pitmen N, as shown. The crank-shaft projects to one side of the binder, and has mounted on said projecting end a sprocket-pinion, O, which is engaged by an endless sprocket-chain, P, which transmits motion to the various parts of the binder, as will be readily understood upon reference to Fig. l. The projecting end of the crankshaft is angular in cross-section, and the sprocketpinion is loosely mounted thereon, so that while the said pinion serves to impart a to tary motion to the said shaft it at the same time allows the said shaft to move longitudinally without disengaging the pinion from the sprocket-chains. 0

S designates a stationary metallic strip secured to the upper ends of the bars L, and projecting over the upper edge of the movable deck to prevent the grain passing backward from the same.

From the foregoing description, taken in connection with the accompanying drawings, it is thought that the operation and advantages of our device will be readily understood. 10o

The cut grain is carried up the elevator B, and deposited thereby onto the movable lower deck, as will be readily understood. The sprocket-chain P is set in motion by the master- 5 wheel and the intermediate gearing, and transmits a rotary motion to the crank-shaft M through the pinion O, and the said crank-shaft imparts reciprocating motion to the movable deck through the pitmen N, as will be readily 10 understood. The movable deck will thus be constantly in motion, so as to prevent the grain clogging thereon, and by reason of the ceding-pins H the grain will be fed to the inding mechanism evenly and steadily so that the work required of the binding-needle 1 will always be the same, and the strain on the machine consequently reduced by preventing the grain accumulating and clogging up the slots I I.

By our device the grain is constantly removed from below the upper end of the elevator, so that it cannot accumulate thereunder.

Our device is composed of few parts and has no complicated driving mechanism, so 2 5 that it can be manufactured at a slight cost.

Having thus described our invention, what We claim, and desire to secure by Letters Patent, is-

1. The combination of the supporting-bars L, the beams Q, connecting the same, the upper beam Q being secured to the harvesterframe and the lower beam being secured to the binder-frame, the movable deck mounted on the bars L, mechanism for reciprocating said deck, and the strip S, secured to the bars L and projecting up over the upper edge of the deck, as set forth.

2. The combination of the bars L, the beams Q, connecting the same, one of said beams being secured to the harvester-frame and the other one being secured to the binder-frame, the longitudinally-slotted strips K, secured on the bars L, the movable deck, the studs depending from the deck and engaging the slots in said strips K, the crank-shaft mounted on the bars L, the pitmen connecting said shaft with the under side of the deck, and mechanism for rotating said shaft, as specified.

In testimony that We claim the foregoing as our own we have hereto aflixed our signatures in presence of two witnesses.
